' 2 Claims. (61. 173*263) A My invention relates to improvements lnwire. The connecter-to which :my invention is apconnecters such as are used for securing a tap or plied comprises a bolt I formed with a diametrilead ofi wire to an electric current supply wire, cal open ended slot 2 therein, the slot opening my invention being more particularly directed into the nut receiving end of the bolt and 3 is a towards this type of device comprising a bolt nut receivable upon the bolt for closing the slot 5 portion having a di'ametrical open ended slot and securing the contained wires in place. therein for the reception of the wires and a nut 3 contains a washer element comprisnut threadable upon the bolt for closing the ing. a block 4 diametrically positioned within the slot and securing the wires in 'place, and the orifice in the nut and formed at its wire =conta'ctobject of my invention is to furnish this type of ing end with a T-s'hapcd head 5 having a wire 1 device with an extension element for receiving e g groove 6 therein, the ends of the greeve the nut" when it is unthreaded from the bolt so eing chamf red to pr vent m eutting the that 'the nut cannot be entirely removed. from wire. The lower end of the block 4, which is free the connecter thus obviating the loss of time and within the nut, is provided with a pair of lugs J trouble'which frequen 1y occurs if the nut is in 7 e t outwardly r u d t ed e of the'elifiee in advertently dropped uring installation. the nut so as to retain the washer element in A further object of my'invention is to so con- P e Washer l nt s o Slightly s struct my device that the addition of the nut ,widtli than the slot 2 to-enable it to freely'slide supporting element does not materially increase therein, and as one of its functions, prevents the its cost and a still furtherobject of my invention leg portions formed by the slotted bolt from be- 20 is to utilize such nut supporting element, which inc squeezed together wh n h n i pp d is preferably in the form of a bendable tongue, as' nd i h n d pr a means for locking the tightened nut against ro- For et g the nut 3- from t e m v tation. from the connecter when it is unthreaded from My invention'consistsof a wire connecter cone b lt I furnish a tongue 8 protruding from 25 structed 'and arranged all as hereinaftermore the nutreceiving end of the bolt.

In this case the tongue ll need *50 construction wherein the nut receiving tongue is not be' as long as the tongue 8 as the tongue and hinged to the bolt portion. nut can be swung clear of the open end of the Like characters ,of reference indicate 'oorre-' slot to permit the insertion oi the wires. In the spending parts in the different views in the iormof construction illustratedin the other fig- .5 drawing, J p ures wherein the tongue 8 is furnished, such '55 tongue must be oi suiilcient length to allow the nut 3 to be sufliciently spaced apart from the the nunierals 13 in the drawing are being con-' nected by means of my connecter, the nut 3 is unthreaded from the bolt I so that it is carried upon the tongue 8, this leaves the slot 2 clear for the reception of the wires as illustrated in Fig. 1. .When the wires have been inserted the nut 3 is threaded back upon the bolt and as the nut 3 carries the washer element, such washer element will, under the influence of the nut, bear against the adjacent wire l3 thus pressing the wires towards the head of the slot whereby they are secured in place. The tongue 8 is then bent around into a position to lie against one of the nut faces whereby the nut is locked against rotation. In the form illustrated in Fig. 7, the hinged tongue ll is not used as a lock for the nut.

From my description it will be seen that I have devised a very simple means for retaining a nut against loss in the type of connecter device as illustrated and described, but although I have shown my devise as pplied to this particular type ofconnecter it is to be understood that it has other possible uses and that it is not my intention to solely limit the application of my invention to the specific form of'connecter as shownand described.

What I claim as my invention is:

- -1. In a wire connecter, the, combination with a tending upwardly therein for the reception of wires and a nut threadable upon the bolt to close the slot, of a bendable tongue protruding from the nut reception end of the bolt to receive the nut when it is disengaged from the bolt and adapted to be bent over to engage a side face oi the nut toretain the nut against rotation when it is in position upon the bolt.
